Atlas Copco XA(S) 137 DD, XA(S) 300 DD7, XA(S) 137 DDG, XA(S) 300 DD7G, XAH(S) 107 DD 2010 User Manual

If you are wrenching on an Atlas Copco portable compressor and you don’t have the factory book, you are asking for trouble. I have seen too many guys guess at a continuous regulating system adjustment and end up with a machine that surges or dumps oil out the intake. This 74-page user manual from 2010 covers the XA(S) 137 DD, XA(S) 300 DD7, XA(S) 137 DDG, XA(S) 300 DD7G, and XAH(S) 107 DD models with the Deutz BF4M2011 engine. It is the same document that came stapled inside the tool box on day one. No aftermarket copy, no scanned-in guesswork. This is what Atlas Copco printed in January 2010.

Safety Precautions for Portable Compressors with Generator

Before you lay a wrench on anything, read chapter 1. It runs from general safety through transport, installation, operation, maintenance, and tool applications. A portable compressor with generator creates hazards that a car engine does not: high-pressure oil lines, rotating belts near a hot exhaust, and electrical systems that can arc if you jump terminals wrong. This manual tells you exactly which safety pictograms mean what and what specific precautions apply when you are working near the air receiver or the generator control panel. I keep a copy in the shop truck because the liability stuff matters when a customer wants to sue.

Continuous Regulating System: Adjustment Procedure

Section 3.1.4 covers the continuous regulating system – that is the heart of the compressor keeping delivery pressure steady. The manual walks you through the adjustment without using vague terms like “a little more tension.” It gives you the starting point for the regulating valve setting and tells you how to check full-load condition versus no-load. If you skip the adjustment step, the compressor will hunt, or worse, the safety valve will lift unnecessarily. Page numbers? The TOC puts it under “Main Parts – Compressor regulating system”. Follow it exactly.

Torque Values and Settings of Shutdown Switches

Most of the hardware on these compressors uses standard metric torque values. The manual includes a dedicated table under Technical Specifications – “For general applications” and “For important assemblies.” That is where you find the foot-pounds for the compressor element bolts, the engine mounting, and the oil filter cap. It also lists the shutdown switch settings – pressure and temperature triggers that kill the engine before you melt a piston. Do not guess. One stuck-open valve on the air receiver can cost you a rebuild. Aftermarket manuals often omit these numbers or print them wrong.

Starting and Stopping Procedures – Control Panel Variations

You get two control panel variants in this book: with cold start and without. The generator function for the G-model units (XAS 137 DdG, XA(S) 300 DD7G) is explained separately. Section 4.2 walks you through every pre-start check – oil levels, fuel, air filter condition, and the emergency stop test. Stopping procedure is not just hit the kill switch; it tells you to let the compressor unload first. Skip that and you may hydro-lock the engine next start. The manual is blunt about it.

Preventive Maintenance Schedule and Service Paks

Chapter 5 lays out the preventive schedule hour by hour. It includes oil change intervals, cooler cleaning, battery care, and storage. Atlas Copco uses service paks (bundled kits with filters and gaskets) – the part numbers are listed. If you are a shop that services rental fleets, this schedule keeps downtime predictable. Check the compressor oil level procedure on page? I will not quote a number because the exact page depends on your binding, but the heading “Oil level check” is plain. Do not mix up engine oil with compressor oil – the viscosity requirements differ.

Source Validity: OEM Print vs Aftermarket Copies

When you buy this from AutoRepairManuals, you get the original Atlas Copco PDF – the same one with printed matter number 2954 3170 01, dated 01/2010. That matters because aftermarket resellers often delete pages, blur diagrams, or substitute generic torque charts. I have seen a third-party compressor manual tell a tech to torque a cylinder head bolt to 80 ft-lb when the factory spec is 55. That is how you snap studs. This is the real deal. If you need a related model, check the Atlas Copco XRY5 557 Cd, XRXS 567 Cd, XRXS 607 Cd 2010 User Manual for smaller units, or the Atlas Copco XAHS 146 Dd 2010 User Manual – Factory Specs for the next size up. For even broader coverage, the Atlas Copco XAHS 37 DD, XAHS 70 DD7, XAS 47 DD, XAS 90 DD7, XAS 57 DD 2010 User is also available. External reference on general safety for portable compressors can be found at Manual Transmission not related – but if you are dealing with tow-vehicle issues, check the tow vehicle’s manual, not the compressor book.

Working on a Deutz engine or the Atlas Copco screw element requires precision. This manual gives you the adjustment specs for the continuous regulating system, the air filter service intervals, and the brake adjustment procedure if your unit has the towing brake option. The problem solving section lists common faults – low pressure, high temperature, oil carryover – with probable causes in order of likelihood. That alone will save you hours of trial-and-error.

One paragraph that is under 40 words: Do not use aftermarket wiring diagrams. This manual has the correct electrical system description for the 24V control panel.

If you are a home garage enthusiast who bought a used XA(S) 137 DD to run air tools, this manual is for you. You need the rated working pressure and the generator load limits. The data plate section tells you exactly what the numbers mean. Beginners: start with the safety chapter, then the before-starting checklist. Professionals: go straight to the torque values and the continuous regulating adjustment. Either way, Access the Factory Manual and keep it on your tablet by the compressor.

Frequently Asked Questions

Does this manual cover the generator function on the G models?

Yes. Section 4.2.3 specifically covers the generator function for XAS 137 DdG and XA(S) 300 DD7G, including load connection and safety interlocks.

What toque values are listed?

Torque values are given in the Technical Specifications chapter under two tables: general applications and important assemblies (engine mounts, compressor element). Metric fasteners, foot-pounds.

Can I use this manual for older Atlas Copco compressors like the XAS 90?

No. This is specific to the XA(S) 137 DD, XA(S) 300 DD7, XA(S) 137 DDG, XA(S) 300 DD7G, and XAH(S) 107 DD. For older units get the correct factory manual. Using wrong specs leads to damage.

How do I check the compressor oil level without overfilling?

The manual says run the compressor at operating temperature, shut it down, wait 30 seconds, then check the sight glass. Oil should be in the middle of the sight glass. Overfilling causes foaming and oil carryover. Procedure is in Maintenance chapter under Oil level check.
